riginal application filed lebrhary', 1897, Serial No, 622,407. Dividedand application led January 24, 1898. Serial No. 667,703. Again dividedand this application iiled October 7,1898. Serial No. 692,892. (Nomodel.)

To all rtf/tom 'it may concern:

Beit known that I, GEORGE B WEBB, aciti- :cen of the United States, anda resident of lVestiield, in the county of Union and State of NewJersey, have in vented certain new and useful Improvements inType-Vriting Machines, of which the following is a specification.

rThis case is a division of my application filed January 24, 1898,Serial No. 607,703, which latter is a divisional application of anapplication filed by me February 8, 1897, Serial No. 622,407, upon whichLetters Patent No. 599,428 were issued on February 22, 1898, and relatesto what is usually designated as the line-locking mechanism.

XVhile the main objects of my invention are to improve the constructionand operation of what is known as the Remington No. 6 machine, it will,nevertheless, be understood that my improvements may be embodied in'other forms or styles of machines.

My improvements consist in the various features of construction andcombinations of devices, all as will be hereinafter more fullydescribed, and particularly pointed out in the appended claims.

1n the accompanying drawings, Figure 1 is 1a rear view of the upperportion of the machine and showing more particularly the linelockingmechanism, the type -bars, key-1e vers, &c. being omitted to avoidcomplication and to enable the parts to be exhibited on a larger scale.Fig. 2 is a vertical section taken -at the line fr r of Fig. 1, and Fig.3 is a plan view of the escapement-lookin g device, shown also in Figs.1 and 2.

In the several views the same part will be found designated by the samenumeral of reference.

At the rear side of the machine is a bar or rod 1, preferablyrectangular in cross-section and pivotally secured at its ends inuprights or standards 2 on the top plate 3, one at the right and theother at the left hand side thereof. The pivots of the bar are made inthe form of screws 4, having plain or un- -threaded ends 5, which enterplain holes in the ends of the bar or rod 1, the threaded portionsscrewing into threaded holes in the standards. This bar is formed on itsrear side with a series of teeth 6, forming a series of intermediatenotches, which may be equal in number to the teeth and notches of thecarriage-feed rack 7 and the number of letter-spaces to which thecarriage 8 is susceptible. The said bar is preferably graduated on itsupper face or marked with numerals and lines to correspond with thenumber of notches or teeth thereon to facilitate the adjustment of thevarious devices movably mounted thereupon. ranged parallel with the pathof travel of the carriage and has a slight endwise movement upon itspivots or centers for the purpose of locking the escapement mechanismand through it the printing mechanism at a predetermined time, as willbeA presently described. Projecting downwardly from said rocking andendwise-moving bar is an arm 9, Y

which has a rearwardly-extended portion 10, that is slotted and engagesWith an upright projection 11, that slides in a slot in the top plate,the said projection being at the rear' end of a push-rod 12, which issuitably supported by bearings 13 under the top plate at the left-handside and which projects slightly beyond the front end of said top plate,Where it is provided with a head or key-button 14. Surrounding saidpush-rod is a coiled spring 15 for returning it and the rocking bar 1,which .is connected thereto, as above explained.

The device which is provided to yarrest the forward movement of thecarriage and at the same time by the power of the carriage-drivingspring in the drum or holder. 16 to communicate endwise movement to therocking bar 1 to lock the escapement mechanism performs also a functionin the alarm or bell mechanism; but I shall describe more particularlythe carriage` arresting and line-locking functions of the device, whichgenerally is an oblong box-like structure 17, surrounding or embracingthe sliding and rocking bar and provided interiorly with a spring toothor dog (not shown) adapted to engage any of the notches on said bar. Thesaid dog is formed The said bar is ar- 4 at one end of a lever pivotedWithin the box and provided at its opposite end with a coiled springadapted to maintain the dog in engagement with a notch on the rockingbar. A cam or eccentric (not shown) having a handle portion 23 isprovided on orin said device 17 to enable the dog or detent to bewithdrawn from the notch by either a right or left hand movement of thehandpiece or lever, in order that the locking device, box, collar, orslide 17 may be adjusted or moved to any desired point on said bar. Thedetail construction and arrangement of the parts just described will befound' more fully illustrated in my aforesaid patent, No. 599,428. Onthe inner side preferably of said sliding box or device is mounted anindex or pointer 25, which cooperates with the scale or grad nations onthe upper side of said bar to facilitate the adjustment of the device.At the locality of said pointer is a lug or abutment 26, which isadapted to receive a projection 27 at the lower free end of a pendentarm or plate 28, secured on the rear end of a long pivot or rock-shaftarranged on the carriage at right angles to the locking-bar and providedwith an arm 30, to which is attached an adjustable Weight 3l, that tendsto maintain the said pendent plate or arm in a substantially verticalposition. The said rock-shaft is supported at its outer or rearmost endin a lug 32 on the left-hand side of a rearwardly-projectingcarriage-arm 33, which is forked at its extremity to embrace a collar34, that slides on a guiding-rod 35, and the inner or forward end ofsaid rock-shaft takes a bearing in the carriage 8. Surrounding saidpivot or rock-shaft is a small coiled spring 36, attached at one end toa collar 37 on said shaft and at its other end to another collar 38,also on said shaft, and the spring at its latter end is prolonged ormade straight, so that in the normal position of the pendent arm orplate 28 the extremity of the straight part of the spring bears againstthe said carriagearm 33. This spring acts against the weighted arm tomove the pendent projection slightly forward when the carriage-arrestingand linelocking mechanism is released. This mechanism is more fullyillustrated in my aforesaid patent, No. 599,428.

On the under side of the rocking bar l at a point slightly on the rightof the escapement mechanism is fixed an angular or L- shaped arm 45,which may be riveted to the said bar, as shown. The said arm projectsrearwardly at right angles to the said bar and then laterally toward theleft and parallel with said bar. The free end of the said arm is adaptedto pass in front of an upward projection 47 at the rear edge of theescapementdog 48 when the said bar l is moved toward the left by reasonof the contact of some moving part of or on the carriage with any of thecollars which arrest the leftward movement of the carriage, and Whenthus moved the said arm prevents the dog holder or rocker fromoscillating and the printing mechanism or type-bars connected thereto(through the universal bar'and the key-levers, as customary) fromprinting or being moved to an extent sufcient to enable the impressionof the type on the paper in case the key-levers should be struck afterthe arm has passed in front of the projection 47. The escapement-dog 48is attached to and forms a part of the usual rocker-arm 49, and whichrocker also carries the pivoted or yielding escapem ent-dog 50,therocker vibrating at right angles to the barl.

The locking of the escapement mechanism is effected in the followingmanner: Vhen the projection 27 on the pendent arm or plate 28 strikesthe lug 26 on the box or collar on the bar l, the said bar is caused tomove endwise toward the left for a short distance, as above explained,and in moving in this direction the arm 45 slides in front of the flangeor projection 47 of the dog-rocker, and thus prevents the dog holder orrocker from vibrating forwardly, as shown by the dotted lines at Fig. 8.Vhen the carriage has been arrested and the dog-rocker locked,thecarriage may either be returned for the beginning of a new line or therocking bar may be tilted by means of the push-rod 12 to raise thelocking-arm and depress the lug 26 and to enable the pendent projection27 to step over the lug to permit more characters to be printed on theline. A small coiled spring 5l is employed to restore the rocking barand arm 45 to their normal positions when the line-locking projections26 and 27 are separated. The locking of the dog-rocker may be eifectedat or during the rst half of the letter-space movement, the remaininghalf of the letter-space movement being permitted by reason of thecapacity of the pendent projection 27 to yield under the superior powerof the carriage-driving spring. On releasing the dog-rocker 49 bytilting the rocking bar l the latter is moved back toward the right bythe spring 5l,and the pendent projection or contact 27 is vibratedslightly toward the left by its coiled spring 36, thereby insuring thependent projection riding over the top of the lug or contact 26 on thecollar mounted on the rocking bar, and hence preventing any rengagcmentor relocking of these devices which would interfere with the furtherprogress of the carriage. When the pendent projection has passed by thelug on the rocker-bar in any case and the carriage isreturned, theright-hand side of the pendent projection strikes against the left-handside of the lug, and the pendent projection is tilted in a reversedirection to enable it to pass by said lug, whereupon the Weightattached to said projection restores it to its normal position. Thependent projection acting upon an inclined ledge 53 is adapted to rockthe bar 1 and to cause the alarm to be sounded several spaces before thelocking or intercepting of the escapement, the said bar having on itsunder side a bell-hammer arm 54, adapted to strike a bell 55 upon rcoIIO

the release of said bar when the pendent projection escapes from thesaid ledge.

The feed-rack 7 engages with a pinion 56 on the inner end of a shaftarranged to rotate in a fixed housing 57, and at near the rear end ofsaid shaft is mounted an escapement-wheel 58, with which the dogs 48 and50 cooperate in the usual manner. The carriage is connected to thespring-drum through the usual strap or band 59.

Vhat I claim as new, and desire to secure by Letters Patent, is-

l. In a type-writing machine and in a linelocking mechanism, thecombination of a carriage, a bar adapted to slide endwise, an arm orprojection fixedly attached to the said bar, an escapement-rockervibrating in a direction at right angles to said bar and adapted to bearrested by the said arm or projection when the said bar is slidendwise.

2. In a type-writing machine and in alinelocking mechanism, thecombination of a carriage, a bar adapted to be slid endwise thereby, anarm or projection Xedly attached to said bar and having a portion whichis disposed parallel with said bar, and an escapement-rocker vibratingat right angles to said bar and carrying a projection which is adaptedto contact with said parallelly-disposed portion when the said bar isslid endwise.

3. In a type-writing machine and in alinelockin g mechanism, thecombination of a carriage, a bar adapted to be slid endwise thereby, anL-shaped arm iixedly attached thereto, and a dog-holder adapted to bethwarted in action by the interposition of the free end of the saidL-shaped arm when the bar is slid endwise.

t. In a type-writing machine and in a linelocking mechanism, thecombination of a carriage having a contact device, a rocking and longitudinally-movable bar having` also a contact device and also anattached locking-arm, a vibratory dog-holder having a projection adaptedto be intercepted by said arm when the bar is slid endwise by theengagement of the said contact devices, and a release-key for rockingsaid bar and throwing the said arm up out of the path of vibration ofthe projection on the dog-holder.

5. In a type-writing machine and in a linelocking mechanism, thecombination of a carriage having a contact device, arocking andlongitudinally-movable bar having a contact device, a locking-arm fixedto said bar, a dogholder having a projection adapted to be i11-tercepted by said arm, a release-key for rocking said bar and throwingthe arm up out of the path of vibration of the projection on thedog-holder, a spring for sliding the bar back to its normal endwiseposition and a spring for rocking the bar back to its normal horizontalposition.

6. In a type-writing machine and in a linelocking mechanism, thecombination ot' a carriage, an endWise-movable bar, a locking-barsecured thereto and projecting parallel therewith, and an escapementmechanism including a dog which is formed or provided with an integralupwardly-extending arm or projection to engage said locking-arm when thebar is slid endwise.
